Nirvana Hammocks use a polyester rope blend, balancing cotton's softness with polyester's durability. The spring bar is made from hardwood, 5 times denser than pine, cedar, and redwood, and ages naturally to silver grey. The rope bed features a double-latch weave, eliminating the need for knots. Nirvana uses 15% more rope than competitors and all hanging hardware is zinc-plated for rust protection and longer outdoor life.
